Again, please tell me if there is a better way to do this.

While testing docker, frequently I need to start/stop/rm containers. I got real sick of having to ls them and copy paste the container ID.

Using this alias, I just have to remember a single part of the name of the container, and I will get the container IDs that can then be included as part of another command:

$ alias dcl='_dcl(){ docker container ls -aq -f name="$1";}; _dcl'

$ dcl snikket
b3fcbc808cc9
1947885fbb24
054d67d2e8b9
d8fe9df5f61f

So now that I’m getting a list of IDs, I can easily, for example, pause all of them:

$ docker container pause $( dcl snikket )
Error response from daemon: container  is not running
Error response from daemon: container  is not running
Error response from daemon: container  is not running
Error response from daemon: container  is not running

The containers weren’t actually running, but this shows the alias working.

dcl obviously stands for ‘docker container ls’

    You can use the container names to address containers. Whether this is a randomly generated name (docker run… with no --name flag), the compose working dir and service name, or the compose container_name var.

    I also rarely use the container command. docker is sufficient, or docker compose ... while in the working dir of a given compose stack.
